Abstract: The present disclosure relates to an apparatus and method for anaerobic wastewater treatment with a membrane, which effectively generates biogas and suppresses fouling on a membrane surface by performing anaerobic treatment to wastewater. The apparatus for anaerobic wastewater treatment with a membrane includes: an anaerobic reactor for performing anaerobic treatment to wastewater and generating biogas; an anaerobic membrane bio-reactor for filtering wastewater discharged from the anaerobic reactor by means of a membrane module and providing an additional anaerobic treatment space for the wastewater; submerged membrane modules provided in the anaerobic membrane bio-reactor to filter wastewater; rotating disks provided at both sides of the submerged membrane module to induce turbulence to the wastewater by means of rotation; and a second media provided in the anaerobic membrane bio-reactor to circulate according to the flow of the wastewater so that foulants on a surface of the membrane module are detached.
